podman pod 处于不一致状态，无法删除

过去，使用 podman 删除 pod 失败了，现在我处于不一致的状态，我不知道如何修复。显然，磁盘上删除了 infra 容器的存储，但 podman 仍然认为该容器存在。我的 root 实例和 rootless 实例都有一个这样的容器。请帮我弄清楚如何清理它（删除对不再存在的这个 pod 的引用，并删除 infra 容器……）

主机系统是Fedora 29 Silverblue。

podman 输出...

假设您不想$HOME/.local/share/containers直接删除，则需要编辑一些 JSON 文件。

  1. podman如果可能的话，关闭所有容器。
  2. 查找 SHA256 条目，$HOME/.local/share/containers/storage/overlay-containers/containers.json除了您尝试修复的容器的条目之外，您还应该看到每个有效容器的条目。
  3. 删除您希望 podman 忘记的与 SHA256 容器相对应的完整条目。

以下是我系统中的一个例子，用来jq让事情变得漂亮。我目前有两个 podman 容器：fcb8454b75ad / freedv 和 8456a27c0f4c / tang。如果 freedv 容器像你的一样“消失”，我会删除第二部分，包括第一部分右括号后面的逗号，保留最后的右方括号：

  },  <-- Remove the comma but not the closing brace.
  {
    "id": "fcb8454b75ad8
...
      "ProcessLabel": ""
    }
  }  <-- Remove this.
]    <-- Leave this

这是修改之前的完整文件：
